Refactorings and added ability to subscribe to topics.

[BrettSheleski]

I was going to write a node app to handle my need to publish to my MQTT broker from my Plex server using Plex's webhooks feature. Instead of reinventing the wheel, I came across your project, forked it, and added what I needed.

Things I did:

• Refactored much of what you had written as middleware where appropriate.
• Ability to specify the topic from query parameter
• Ability to specify the message path from query parameter
• Ability to specify uploaded files (needed for my case with Plex Webhooks)
• Feature to subscribe to topics. This will tell the MQTT Client to subscribe to the topic specified and will proxy any message received to the HTTP response. I did this just because I thought it would be easy to do.

Nothing I did should have modified existing behavior. Of course you may want to doublecheck that :).

Is there any interest in merging this? I do have some other changes that you may also be interested in.

Wow! Impressive work. Sorry for a delayed response. I've merged you changes into the http_to_mqtt repository and will give you access to this project.

Cool. Thanks!
